A Case of MALT Lymphoma of Buccal Area / 대한이비인후과학회지

ABSTRACT

Mucosa-associated lymphoid tissue (MALT) lymphoma, known as a distinctive type of non-Hodgkin's lymphoma, is an extranodal marginal zone B-cell lymphoma. It most frequently occurs in the stomach but has also been described in various non-gastrointestinal lesions, such as the salivary glands, conjunctiva, thyroid, orbit, lung, breast, kidney, liver, and prostate etc. It occurs very rarely in buccal mucosa. The MALT lymphoma tends to remain localized for long periods and respond to locally direct therapy. We recently encountered an 80-year-old male presenting with a foreign body sensation in the oral cavity; he was finally diagnosed as MALT lymphoma. We report this rare and unique case with a review of literature.
